Be it known that I, HJALMAR" Swanson, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented anew and useful Improvement in Punching-Machines, of which the following is a specification.

This invention relates to perforating or canceling machines and the like and has for its general object the provision of a simply constructed though highly eliicient machine of this character, which embodies, among other features, a novel automatic feed of the material to and from the punching or can celing mechanism,the .feed of the-material being so timed with relation to the operation of the punching or canceling mechanism that material is progressively advanced into the path of thepunching mechanism, held in position sufliciently longlito permit the punching mechanism to perform its operation, and is then further advanced to the point of discharge.

A. more detailed object of the invention is to construct the feeding mechanism in such manner that, although highly eflicient" for performing its function of feeding the material, parts of said feeding'mechanism are adapted, on encountering undue or destructive pressures such as might occur if the machine becomes jammed, to yield and to prevent such pressures from causing injury to parts of the machine.

The invention has for other objects such other improvements in construction and advantages in operation as maybe found to obtain in the mechanism hereinafter described or claimed.

" limiting the claimed invention specifically to such illustrative instance orinstances:

The same characters of reference de sig-' nate the same parts throughout the several views.

In the illustrated embodiment of the invention, the machine is especially designed for the purpose of perforating packages or bundles of bank convenience the machine will be invention. Features of construction of the notes and the like, and for present description of the 'machine are readily susceptible of other uses, however, andit is manifest that the confined to this use of the scope of the invention is by no means confined to the speclfic use and specific embodiment herein described as an illustrative e'xample.

Referring to the drawings, -the -various parts and the instrumentalities of the ma chine aresupported bya table or platform 21. li/lounted on the platform 21 are pedestals 22' and 23 provided along their facingv vertical sides withguides 24: and 25 "and also having at their upper ends bearings 26 and 27 V which mutually support the mainhorizontal' driven shaft 28. A pair of eccentrics 29 is mounted on the aforesaid shaft 28 and supported by the respective eccentrics 29 are collars 30 respectively provided with depending vertical arms 31 which are mutually pivoted at their lower ends to a frame 32 mounted for vertical sliding movement in the hereinbefore mentioned vertical guides 24 and 25. The frame 32 supports. a plurality of punches 33 adapted to pass through alined holes in a horizontal guiding block 34- supported by the lower ends of the pedestals 22 and 23, and to cooperate with dies formed in the die block 35 mounted on the platform or table 21. With this con struction, the punches 33 are lowered and elevated into and away from the dies formed in the die block 35 at each rotation of the main driven shaft 28. I r

The punches 33 whichcooperate with the dies formed in the die-block 35 are respectively positioned on the opposite sides of the median lines of stacks of separate sheets of material such as the bank notes illustrated in Fig. 14, as each stack of said sheets is fed into punching position. During the punching operation, the punches themselves act to hold all the sheets of a stack being punched, and the effect of the punching operation is to punch holes in each stack of sheets or bank notes, the holes being located within the edges of the bank notes and re spectively positioned in thefour quarters of each bank note of a stack, with the result that the bank notes are mutilated, prelimi-v nar to cuttin or slicin the stack of bank notes for shipment for purposes of redemption; consequently nopart of the punched bank notes would be again available for circulation.

In accordance with the invention, means is providedfor intermittently clutching the shaft 28 with a power source, so as to effect an intermittent operation of the shaft 28 and punch. Journaled on the driven shaft 28 is a driving fly wheel 36 adapted to be connected with a suitable source of power,

such as an electric motor (not shown), and fixedto a gear 37 in mesh with a c'am-operating gear 38 that is rotatably mounted on a short stub shaft 39 supported by a bearing 40 projecting from the pedestal The cam operating gear is provided with an eccentric groove 41, within which runs a roller 42 thatprojects from the face of the 43. The upper end of said cam 43 is formed with, an arcuate recess 44 extendin vinwardl from the :to" face thereof ant havin its axis substantiall coincident with the axis of rotation of the hereinbefore mentioned driven shaft 28. Said driven shaft 28 is provided with'a collar 45. adapted. to enter the arcuate cut away portion 44 of the cam 43, when the latter is in its elevated position. Formed in the hub of the driving fly wheel 36 is a longitudinally extending socket 46' within which is mounted a movable clutch pin 47. As shown more particularly in Fig. 9, the outer end of such clutch pin passes through the gear 37 and is adapted to span the peripheries of the collar 45 and upper end of the cam 43; the inner end of said pin bears against a coiled spring 48 positioned in the inner end of the socket 46. An arcuate groove 49 terminatingat its opposite ends in approximately radial shoulders 50, 51 is cut away from that face of the collar45 in juxtaposition with respectto the faceof the gear 37 and the upper end of the cam 43 is formed with a recess 52 having an inclined vertical face 53, as shown.-

moreparticularly in Fig. 11. The cam 43 has a slotted plvot on the stub shaft 39 as indicated at 54, to permit up and down,

movements of the cam, effected by thetravel of the roller 42 in the eccentric groove 4i.

of thergear 38. r

The ratio of the driving fly wheel 36, gears 37 and 38 and other parts is such that, in the present embodiment, the driven shaft 28 is clutched to the driving fly wheel 36 and.

makes a complete revolutionon every third revolution of the. driving fly wheel 36,. in other words, the cycle of operation is such that each operative movement of the driven shaft 28 is succeeded by two idle revolutions;

of the driving fly wheel 36 during'which the driven shaft 28 is stationary. This mode of operation is accomplished by the abovedescribed cam controlled clutch mechanism in the following way: gear, 37 is constantly driven by the driving fly wheel 36 as well as reciprocatory movement of the cam 43, to shift the latter intermittently into and out gear 38 in mesh with gear 37 the rotation.

of the eccentric groove 41 causes'a vertical of positionfor engaging the pin 49which is constantly traveling in a circular path. As-

suming that the shaft 28is stationary and that the pin 47 is in a retracted position, the

to the shaft 38 and the latter makes a com plete revolution. The parts are so timed, however, that toward the end of thefrevolution ofthe shaft 28 the cam 43 is moving ,toward the collar 45; whileat the same time the pin 49 is being carried toward the inclined vertical face 53- at the upper end of the cam 43. Just about at the end of the revolution ofthe shaft 28the pin is brought into engagement with said inclined face 53 of the cam 43 and riding along said incli face to the high point 55 is retracted'into position for releasing the collar 45 and shaft 28 from the fly wheel 36 whereupon said shaft 28 stops turning. When the pin 47 moves out of engagement with the cam, it travels idly over the face of the now stationary collar 45 and on again arriving at the groove 49 is again retracted by the cam 43. On the third revolution of the flywheel, however, the cam 43 is in its retracted position and the pin is permitted to pass'along the groove 49 until it strikes the shoulder 51, so as to effect another complete revolution of the shaft 28. r

Each revolution of the shaft 28 through the eccentrics 29 and other connection hereinabove described effects first a down and thenan up stroke of the frame carrying the punches 33. A constantly tensioned band brake- 56 is applied to a brake drum 57 mounted on the shaft 28. This causes the shaft 28 to stop quickly whenever the clutch pin is released and prevents any idle movement of the shaft.

proved feeding mechanismfor feeding material-into position for being punched While the punches 33 are idle, holding the material in punching position on the down and up stroke of the punches, and then feeding the material to a point of discharge. For this purpose, the fly wheel 36 is provided with a sprocket 58 that is geared by a sprocket chain 59 with a sprocket 60 r otatably mounted on the intermittently operable shaft 61 journaled in suitable bearings extending above the table or platform 2.1. The shaft 61 is provided with'a brake drum 9? encircled by a constantly-tensioned brake band 98 for stopping the shaft quickly and preventing overthrowyduring its periods of.

rest. Sprocket 60 is fixedto'agear 62 that meshes with a cam operating gear 63 that is adapted to reciprocate a'cam 64 similar to the before mentioned cam 43 andcontrolling the operation of a clutch pin for connecting or disconnecting the sprocket 60 with respect to the shaft 61. The'mechanism'for clutching the shaft 61 to the sprocket 60 is similar to the clutch mechanism hereinabove described for clutching the fly wheel 36 to the driven shaft 28 and need not be redescr'ibed here it will be sufficient to state that the shaft 61 is driven bythe'sprocket 60 while the punches areidle so as to advance material into or out of their path. The shaft 61 constitutes the drive shaft for.

' pair of feed chains 65 and 66which pass over sprockets 67 fixed-on the shaft 61, thence through an opening in the platform 21 to two pairs of idle sprockets 68 and 69 V mounted below the platform 21 and thence through an opening in said platform to a pair of idler sprockets 70 mounted above said platform. The upper operative reaches of the feed chains 65, 66 extend along the opposite sides of the die plate 35, as shown in Fig. 6,.and between a pair of vertical The invention further provides an imguides 71- mounted above the platform 21. Projecting from the inner edges of therespective chains 65,66 and'arranged oppo sitely with respect to each other are up standmg guiding fingers 72 positioned'at, suitable points along the feed chains 65, 66.

Each finger is yieldably mounted on its the finger to yield rearwardly, should it en counter anvobs'truction, such as might'occur from a amming of material beneath. the punches while the chain is traveling along the side of the die plate 35. This construc V Y tion prevents damage or breaking off'of the feeding lingers, as theycan readily yield and pass beneath an accumulation of material.

Aghorizontal feed plate '16 is mounted fluslrwith the die plate 35 and is'preferably provided with a depending apron 77,: as shown more particularly in Fig. 4. Atthe discharge end of the die plate 35 is a discharge plate 78 having ahorizontal portion a 79 flush with the die plate and a down? wardly inclined portion 80 over whichthe punched material discharges; from the horizontal portion 79 of the discharge plate 78t'o the downwardly inclined portion or chute 80 the punched material .passes beyond the influence of the feed chains andgravitates to the dischargepoint.

As stated, the present machine is particu-. larly adapted for punching bundles or packages of bank notes and the like, such as are indicated, at 81 in Fig. 14. For holding a stack of separate sheets of material, such as a package of bills, in position over the die plate 35 the guiding plate 34is provided with a leaf spring 82' which incurves beneath the plate 34, as shown in Fig. 4; The packages of bills are deposited one by one on the feed plate 7 6 and a pair of oppositely disposed fingers 72 moving into engagement with the packageofcbills pushes the same forwardly until it arrives in punching position beneath the guide plate34. 'On arrival of the package in such position the chains stop moving and the package is held in posi-v tion for being punched by the leaf spring 82 which coiiperate s with the two fingers 7 2 in engagement'with the rear edge of the package. After the punches have descended toperforate thebills and have, been retracted, the intermittently operating chains advance In passingv the package from the punching position over the horizontal portion 79 of the discharge plate 78 to the downwardly inclined chute 80, whereupon the punched package passes beyond the chain and gravitates to a stacking mechanism. i

The stacking mechanism is constructed in the following manner: driven by the sprocket 60 is a constantly rotating sprocket 83 that is geared by a sprocketchain 84 with a sprocket 85 mounted on. the stacker shaft 86. Said shaft 86 is provided with a pair of stacker cams 87 that are adapted to move through slots 88 formed in an apron 89 depending from the lower end of the discharge chute 80. Each cam is composed of a pair of oppositely disposed arms 90, 91 respectively formed with oppositely extendingrecesses 92, 93 and withoppositely. extending curved presser faces 94-, 95, the presser face of one arm merging into the recess of the opopslte arm, as shown. Mounted 1n front of the depending apron 89 is an inclined stacker chute 96 of proper dimensions next package of bills discharged by to receive the packages of bills, arranged in substantially uprlght position, as shown m Fi 4 The cams 91 are constantly rotated in a: counter-clockwise direction'by the shaft 86 and when a package of perforated bills arrives at the lower end of the chute 80 it first passes into engagement with the recesses 93 I or 92 of the pair of cams. As the-recesses pass, during the movement of the cams,

from beneath the package of bills, the latter is permitted to fall between a previously stacked package and the apron 89. The receding movement of the recess 93, for example, is accompanied by a movement of the presser face 94 or 95 toward the falling package of bills and the latter presser faces engaging the face of the package, by reason of their curvature, push the package, and the row of previously stacked packages forwardly in the chute 96 to make room for tlhe t 1e chute 80.
